Amorphous activated carbon materials and methods for producing the same

摘要

A method for producing an amorphous activated carbon material includes heating a carbon precursor to a temperature effective to form a partially-dense amorphous carbon, and activating the partially-dense amorphous carbon to produce an amorphous activated carbon. To facilitate efficient activation of the amorphous carbon, the carbonization is controlled to produce an amorphous carbon material that, prior to activation, has a density of from 85% to 99% of a maximum density for the amorphous carbon.

1. A method for producing an amorphous activated carbon, the method comprising:
providing a carbon precursor; heating the carbon precursor to a temperature in a range of 925° C. to 975° C. to form a partially-dense amorphous carbon; and activating the partially-dense amorphous carbon to produce an amorphous activated carbon, wherein the activating comprises: mixing the partially-dense amorphous carbon with an inorganic compound to form a mixture; heating the mixture to a temperature of from 300° C. to 1000° C. to form a pre-activated carbon; and removing the inorganic compound from the pre-activated carbon to form the amorphous activated carbon.
